clear, and exact description.

rlhis invention relates to goggles, the object being to provide a way ofutilizing the well known and popular' style of nose bridge known as thesaddle bridge, without producing the wide pupilary distance whichordinarily accompanies the use ofthe saddle bridge.

further object of the invention is to provide a way of attaching thebridge to the lens rims in goggles which will furnish a very strong andrigid' structure.

'lhe well known saddle bridge consists of an arch-shaped memberaccurately fitting and adaptecLt-o rest upon, the bridge of the nose,and having its extremities reversed or looped so as to formforwardlyextending arms ,which are attached to the` `outside of the lensruns.

Such a bridge when interposed between the lens rims, separates thelatter a considerable distance and spaces each of the rims from thesides of the nose a distance equal to the distance between the extremityof the bridge and the arched portion. The rims, therefore, encroaeh uponthe eye and do not hug the sides of the nose closely so that the rangeor angle of vision is more or less obstructed and the pupils of the eyesare not directly opposite the centers of the lenses. My improvedattachment between the bridge and the lens rims consists i'n securingthe reversed extremities of the bridge to the inner surfaces of therespective rims. In this way the rims occupy the spaces between theextremities and the arched portion of the bridge and are thus nearertogether and nearer to the sides of the nose so that the pupilary.distance of the goggle is reduced.

My invention will be described in detail in connection with theaccompanying drawing. wherein Figure 1 is a plan of one form of goggleto which my invention is applied, a portion being shown in section; andFig. 2 is a plan of a portion of a pair of goggles showing a bridge ofthe same character as illustrated in Fig. 1. but attached to the rimsaccording to the plan generally in use prior to my invention.4

he goggle consists essentially of the two lenses 1-l, which may be ofplain glass or glass having focalv power, as desired. These lenses areset inthe forward` edges of cupshaped rims 2, such rims havingconsiderable `depth so as to protect the eyes from foreign mattersentering around the edges of the lenses. The goggles as shown are alsovequipped with temple guards 3-3 consisting of wire gauze set in suitablecurved frames which are pivoted at 4-4 to the lens vrims and are adaptedto be folded inward for compactness when. the goggle is not in use. Tothe outer extremities of the rimsl are pivotally attached the temples 5,which, in this case, are adapted to.y be folded forward when not in use,against the front faces of the lenses.

6 indicates the well known saddle nose bridge comprising the archedportion 7 shaped as to spread, curvature and inclination to t snuglyupon the bony structure at the base of the nose and hold the lenses atsuoli a distance from the eyes as not to interfere with the eyelashes.The extremities of the arched portion? of the bridge are rel versed soas to form a loop at each end of the bridge, such extremitiesbeingindicated by 8-8. rlhese extremities 8 are attached to therespective rims by passing the rims into the space between the sides ofthe arch 7 and the extremities 8, thusbringing the latter inside of therims, and then securing the said extremities by means of solder orotherwise, firmly against the inner surfaces of the rims. For additionalrigidity, a brace 9 may be spanned across from one rim to the otherabove. the bridge with its extremities soldered to the exterior of therims, but this brace is not a feature of my invention. It will be seenthat by placing the lens rims inside of the loops at the ends of thebridge, the rims are brought nearer together than they are when theextensions 8 are secured to lthe outer surfaces of the rims. This latterconstruction is shown in Fig. 2 and is the construction heretofore invogue. The extensions or extremities 8 are then secured directly to theouter surfaces of the rims 2, and by comparing Fig. 2 with Fig. 1, inwhich the dimensions of all the parts agree, it will be seen that thedistance between the lens rims of Fig. 2 is much greater than it isbetween the lens rims of Fig. l. 0r, in other words, that the pupilarydistance of. the goggles constructed as in Fig. l is less than that ofthe goggles constructed as in Fig. 2.

When the goggles of Fig. l are placed upon the nose, the inner portionsof the lens rims are as near to the sides ofthe nose as they can bebrought, whereas, when the goggles of Fig. E2 somewhat remote from thesides of the nose. Thus, in using the new goggle of Fig. '1, Vision tothe lright and left will be obtained through a widerangle than will bepossible when the goggle of Fig. 2 is used, since the inner edges -ofthe rims are more remote from the pupils of the eyes in the constructionof Fig. l than they are in the construction of Fig. 2. The ability toobtain this short pupilary distance and still use the saddle bridge isof particular importance when the lenses or glasses have focal power,for then it is more essential to have the pupilary distance of thegoggle accurately t that of the eyes so that the vision forward willpierce the centers of the lenses Where least aberration takes place.When the reare used, the lens rims arey versed extremities of the saddlebridge are attached to the inside of the rims, a more rigid connectionis obtained than when they are attached to the outside of the rims, theedges of the rims being seated against the bottom of the loops of thebridge.

I claim l. A goggle comprising lensA rims of greater width than thethickness of the lenses, and extending rearward from the plane vof thelens in combination with anose bridge whose extremities are secured tothe inner surfaces of the respective rims.

2. `A goggle comprising lens rims of greater Width than the thicknessofthe lenses, and extending rearward from lthe plane of the lens incombination with a nose bridge Whose extremities are secured to theinner surfaces of the respective rims and extend therefrom around therear edges of the rims andv forward therefrom.

In witness whereof, I subscribe mypsignature, in the presence of twoWitnesses.
